Coir & preparation
Should I use cocopeat or coco chips?
Start with root-zone behaviour, not the appearance of the material.

Why are fine coir particles collecting at the bottom?
Check whether the material was already layered at filling or has moved during handling. A fine layer can behave differently from the rest of the profile.

Why the root zone matters
Particle distribution affects pore spaces. Screening, mixing and placement all influence the physical structure roots experience in a container.
01 / OBSERVE
Three checks before you change anything
- Inspect an unused sample and a filled container side by side.
- Look for separation caused by repeated pouring or vibration.
- Check whether drainage outlets retain fines or allow material loss.
02 / NARROW IT DOWN
Where does the fine layer appear?
Choose the closest observation for a suggested next check.
Present in unused material
Review the physical grade and mixing instructions with the supplier. Assess a representative sample rather than one handful.
Appears only after filling
Observe the handling process for segregation. Trial a consistent mixing and filling method.
Develops during the crop
Inspect outlet design and media movement before assuming the substrate has chemically changed. Record the timing.
03 / TAKE THE NEXT STEP
Leave with something useful
Keep a labelled sample and a cross-section photo for a physical-grade discussion.
Keep in mind
Do not infer salt content or buffering quality from the amount of visible dust.
